I agree that the web site needs a significant amount of rework.
The APK package manager specifically makes all transactions atomic: if `apk upgrade` returns an error, your system is in the state it was before it was executed. If it does not return an error, your system is now updated.
Rollbacks aren't necessarily as easy to do with "just" APK, but we support Btrfs as a first-class citizen and it wouldn't be hard to make snapshots as an APK pre-commit action if you wanted.
